Team Fortress 2: Terrifying Team Fortress Haunted Hallowe'en Special (2009)

The Haunted Hallowe'en Special, officially known as the Terrifying Team Fortress Haunted Hallowe'en Special, was the first update in what would become annual Halloween events. The update was first revealed in a blog post, followed by an immediate release on October 29, 2009. Aside from fixing a few issues, the update introduced two new maps: Harvest and Harvest Event. The release of these maps was unique as it was the first time that the same map had been released in both a standard and an event variety. The patch also introduced two new hazards: the ghost of Zepheniah Mann, which was exclusive to Harvest Event, and the Pumpkin Bomb, which only appears on Halloween-themed maps. Two new cosmetics were also introduced, the Mildly Disturbing Halloween Mask and the Ghastly Gibus, as was a pack of five Halloween-themed achievements known as Scarechievements. Finally, the patch introduced the Halloween pumpkin; a special pickup item that only appears on Halloween-themed maps and randomly drops when a player is killed.
